Question

5. Identify the different types of
mixtures: Aerated water, oil
and water, sand and water,
smoke, bronze, gun powder​

Answer 1

Answer:

Aerated water like soda water etc., are gas in liquid solutions. These contain carbon dioxide (gas) as solute and water (liquid) as solvent. Air is a mixture of gas in gas. Air is a homogeneous mixture of a number of gases.

oil and sand is liquid solid mixture

Sand and water is also solid liquid mixture

Smoke is a collection of tiny solid, liquid and gas particles. Although smoke can contain hundreds of different chemicals and fumes, visible smoke is mostly carbon (soot), tar, oils and ash. Smoke occurs when there is incomplete combustion (not enough oxygen to burn the fuel completely).

Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon.

The first such explosive was black powder, which consists of a mixture of saltpetre (potassium nitrate), sulfur, and charcoal.
